Method and system for the secure and verifiable consolidation of the results of election processes

ABSTRACT

A method and system for the secure and auditable consolidation of the results of an electoral process, in which local electoral authorities ( 101 ) participate to validate, by generating a validation test ( 106 ), local electoral results. This validation test is communicated to a consolidation module ( 103 ), which will verify that the validation test ( 106 ) has been generated by the appropriate electoral authorities. It will then generate a receiving test ( 107 ), which will contain the result of the validation, which could be the acceptance or non-acceptance of the validation test. The receiving test ( 107 ) is finally sent to the electoral authorities for information of the validation. There are different ways of generating the validation and receiving tests so as to be able to robustly verify the identity of the local electoral authorities ( 101 ) who have participated in the validation of the electoral results and to verify if the validated local electoral results are the same that are going to be consolidated and to preserve the integrity of the official records of the local electoral results.

FIELD OF THE INVENTION

The present invention primarily relates to the field of electoral processes and introduces a secure and auditable method for the results consolidation. The method provides the necessary processes for local electoral authorities, such as the members of a polling station, to communicate electoral results to a results consolidation center in a secure and auditable manner.

The method can be used in results consolidation in remote settings in presential or remote electoral processes.

The invention also relates to a system for implementing the mentioned method.

BACKGROUND OF THE INVENTION

Accuracy in the results is an essential characteristic of any electoral process. The vote recount has traditionally been carried out manually, which results in an unwanted delay in publishing the results, and especially a high probability of committing errors in said recount.

The modernization of electoral systems has enabled speeding up the vote recount and the accuracy in the results by means of using electronic voting devices (e.g. electronic voting terminals or vote scanning machines). These devices enable generating an electronic record of the votes, and therefore performing a faster and more reliable electronic recount. They also make it easier to send both the electronic votes and the local results obtained to a central recount system which allows consolidating the results of different electoral colleges or voting channels. However, the current proposals only contemplate protecting the privacy of the votes or results sent by means of encryption. These solutions do not incorporate measures making it easy to audit the integrity of said local recounts or to identify if these results have been endorsed by the authorities responsible for performing said recount. It is therefore impossible to reliably verify if the local recounts received by the consolidation center have been manipulated before being processed by the consolidation center. Additionally these proposals do not take into account the possibility of consolidating results coming from manual recounts, so they cannot be applied to traditional voting settings.

An example of these proposals can be found in patent document U.S. Pat. No. 7,044,375, describing a system in which a consolidation central of the results of a vote is performed, carried out by electronic means. The system has an acquisition and communication device that is responsible for collecting the votes and/or results generated in the local voting and/or recount machines in the voting premises. This data is encrypted and sent from each local premises to a central results consolidation system by means of a communication channel. The central consolidation system receives the data, decrypts and performs the recount. The consolidation system periodically sends the updated results to a results publication system. As mentioned above, this solution does not incorporate measures which allow protecting the integrity of the data sent to the system central. Nor does it incorporate measures which allow verifying if the sent data has been verified by the local electoral process authorities, rather it assumes at all times that the received data is from a reliable source, without validating such source.

Similarly, patent document US20060196939 describes an electronic voting system including a centralized vote recount system. The local results of each electoral premise is encrypted and sent to a centralized recount system. Said transmission can be online or by means of physically transporting the local recount terminal storage devices. The local storage device has a physical interface allowing it to connect to the centralized recount system in order to download and decrypt the local results. The centralized recount system sends the results to a publication system through a communication network, which publication systems is responsible for disclosing the results.

Neither of the two aforementioned cases proposes actions that help to preserve the integrity of the results. Although in both cases the local results are encrypted before being sent to the central server, which protects them during transmission, they do not consider techniques that assure the integrity of the local results before being sent, nor can they assure the integrity of the end result.

Due to the possibility of manipulation of the results, there are methods which seek to verify (or audit) the accuracy in the result of an election by means of parallel records in different storage mediums. One example thereof are systems which print each vote while at the same time recording such vote in an electronic medium.

The main drawback with parallel vote recording systems is that if one of the records is manipulated, it can only be detected by means of an audit. In the event that a discrepancy is detected in the recount of both records, it is impossible to know which of them has been manipulated, and it is therefore impossible to be certain of which is the correct result.

The present invention describes a method for consolidating results of an electoral process in a secure manner. Said method allows consolidating the local results generated in different local premises or even in different electronic voting channels or platforms. Another object of the present invention is to protect the integrity of the local election results, as well as to check the authorship of the election official or officials sending said local results. The present invention further seeks to generate physical records of the local results and to protect their integrity, as well as to check the authorship thereof.

BRIEF DESCRIPTION OF THE INVENTION

The present invention describes a method for the consolidation of electoral process results which enables electoral authorities to protect the security and auditability of local results of the electoral unit to which these authorities have been assigned. The present invention describes as part of the method, the generation by one or more members of the local electoral authorities of a validation test of the electoral results, which allows at least identifying the members of the electoral authority who have participated in the validation of the local electoral results. The method also describes generating a validation test which is further linked to the validated local electoral results by the members of the local electoral authority who have participated in this validation process. This validation test will be used to verify if local electoral results to be consolidated have previously been validated by the assigned local electoral authorities. The method also provides communicating to the electoral authorities of the result of said verification.

In a basic embodiment, the method comprises the following steps:

-   -   a) The local electoral authorities validating the information of         the local electoral result by means of generating a validation         test which allows verifying the participation of at least one         part of said local electoral authorities in said validation;     -   b) Communicating said validation test to a consolidation module;     -   c) Verifying in said consolidation module that the communicated         validation test of the local results has been generated by the         appropriate local authorities;     -   d) Generating in the results consolidation module a receiving         test for receiving at least said validation test and         representing at least the result of the verification; and     -   e) Communicating to the local electoral authorities the         acceptance or non-acceptance of the local results based on the         receiving test.

The method optionally provides that steps a) and b) are carried out by means of an information transfer module.

In relation to the step of generating the validation test, the invention introduces different alternatives for generating said test such that the test allows identifying the identity of the authorities who have participated in the validation of the local results. It also provides different alternatives by means of using cryptographic and/or biometric techniques for generating the validation test such that it further allows linking said test to the validated local electoral results.

In relation to the verification step, the invention describes different alternatives of verifying the validation test and supported actions based on the result of said validation, such as proceeding to the acceptance or non-acceptance of the local results for their consolidation.

The invention also describes different alternatives for generating a receiving test, including that of including an integrity test generated from the accepted local electoral results, such as a digital signature.

The invention finally describes how the information of the receiving test can optionally be used to protect the official electoral record of the local electoral results. It also describes how the privacy of the validation signature digital and/or the communicated electoral results could be protected by means of using cryptographic techniques.

DETAILED DESCRIPTION OF THE INVENTION

The present invention relates to a method making the secure results consolidation of an electoral process easy, which can be applied both to presential and remote voting settings. The results consolidation is carried out by means of using techniques and processes which allow protecting the integrity and audit of the electoral results.

In this invention electoral process will be understood as any public or private consultation or request for information and a limited or open set of people, based on which a global or partial accumulative or qualitative results will subsequently be carried out. Examples of electoral processes, without the intention of limiting their definition to them, are votes, consultations, surveys, examinations or evaluation tests.

In order to put the present invention into practice, the existence of local electoral authorities belonging to an electoral college or to any other electoral management unit (e.g. district, premises, municipality, etc.) is considered. These electoral authorities could be formed by an electoral committee (e.g. a polling station), one or more local electoral administrators, or a combination of them. The main function of these local electoral authorities is to validate, at least part of them, the local results of their electoral management unit. These local electoral authorities or part of them could optionally also have participated in obtaining the local recount and/or communicating said results. These local electoral authorities or part of them could also be responsible for generating and/or validating (e.g. by means of a signed manuscript) an official record on paper of the local electoral results of their electoral management unit. This record is commonly attached to the physical or electronic votes that have been used for the local recount and sent to the central electoral authorities for their central recount or audit.

Additionally, for the embodiment of this invention the existence of a consolidation module is provided in which the validated local results are normally communicated. This module verifies that said communicated local results have been validated by the corresponding local electoral authorities, and communicates the result of that verification to said authorities. To that end, it is provided that this consolidation module has data input and output means and processing means to receive and verify information related to local results. Information related to the result of the verification is communicated to at least the local electoral authorities. Optionally, depending on the result of the verification, this module can store the results for their consolidation; therefore it could have storage means. To make the remote communication of the local results and of the result of the verification easier, this module could be connected to a communications network and receive the local results and/or the information for the verification by means of this communications network. Therefore at least part of said data input and output means could be an analog or digital communication interface.

Optionally, in order to make the remote communication of the local results and/or generating validation information easier, the existence of an information transfer module is also provided, through which module the local results will be communicated to a consolidation module. For this purpose it is provided that said module has a data input and output interface which allows entering said results and communicating them to the consolidation module. Other additional validation information which may be required by the consolidation module in order to verify if said local results have previously been validated by the relevant local electoral authority can also be communicated along with the local results. This validation information can be generated in said module based on information obtained from at least part of the local electoral authorities. To that end, said module will have processing means in addition to the data input and output interface.

In a preferred embodiment, the invention will begin by means of a first validation phase by local electoral authorities of information of a local electoral result. For the sake of simplicity, it is assumed that the local results can only be validated by the local electoral authorities assigned during the set up of the election, although other entities (e.g. observers) could participate in this process if the electoral process allows it. This validation will consist of generating a validation test for testing the local electoral result information containing information which allows verifying the identity of the authorities who have participated in said validation process. To that end this validation test must contain at least identity information of at least part of the authorities who have participated in generating the validation test. This identity information could be generated from identification credentials, such as a password, a biometric record or any other identity test that may allow uniquely identifying the electoral authorities. The set or combination of these identity tests would form the validation test (VT).

VT=(Id₁,Id₂ . . . Id_(n)) Id_(i) identity test of the authorship i

Said identity information could also optionally be generated by means of mechanisms which allow linking said identity test to the local results information. In addition to identifying the authorities who have participated in the validation, the validation test would thus also protect the integrity of the local results information (i.e., any subsequent modification of the validated local results information would invalidate the validity test).

In a preferred embodiment, this identity information will be generated using cryptographic algorithms, such as a digital signature or a MAC, applied to at least the local result information using at least one password. The password or passwords used for implementing this signature or MAC would be in the possession of one or several members of the local electoral authorities participating in generating the validation test. In this sense, a single password could be in the possession of a single member (e.g. an election administrator) or held by at least one subset of the electoral authorities, by means of using a secret sharing scheme or an equivalent method. In a preferred embodiment based on the existence of a single password, this password will be used to generate a signature or MAC on the local result information (LRI) or on the chaining of said electoral result information with identity tests of the authorities who also participate in the validation process, and who do not have access to the password. As previously mentioned, the identity tests could by any credential uniquely identifying a member of the electoral authority. Finally, the validation test would be formed by at least said digital signature or MAC obtained, or the chaining of this signature or MAC with the identity tests used to generate them. For example:

VT=S(LRI)

VT=S(LRI|(Id₁,Id₂ . . . Id_(n)))

VT=S(LRI|(Id₁,Id₂ . . . Id_(n)))|(Id₁,Id₂ . . . Id_(n))

VT=S(LRI)|(Id₁,Id₂ . . . Id_(n))

In another alternative embodiment, more than one cryptographic password could be used to generate the identity information. In this case the digital signatures or MAC could be generated in a nested manner (e.g. make a digital signature from another prior digital signature) or they could be chained or combined with one another. In either of the cases, one or several of these signatures will be made from of at least the local electoral result information. As in the previous embodiment based on a single password, in addition to the local result information, it also provides using in any of the signatures the identity tests of the authorities participating in the validation of the local result information. In either of the cases, the validation test would contain at least the identity information and optionally the identity tests of the authorities who have participated in the validation.

Finally, as an alternative to the use of cryptographic algorithms, the invention also provides generating the identity information based on one or more biometric records of the electoral authorities participating in the validation. These records must contain at least information related to the local results information. This related information could be all of, part of or one integrity test of the local results. The integrity test of the results could be obtained by means of the application of a cryptographic hash function (e.g. MD5, SHA1 or other equivalents) or a compression function (e.g. GZIP, RAR or equivalents) on the local electoral result information. An example of biometric test related to the local results information, without limiting the method to its use alone, could be a voice record of one or several local electoral authorities mentioning part of the hash value of the local electoral result information. In this sense, the validation test would contain an identity information formed from a set of one or more biometric records of electoral authorities containing the local result information. The biometric records could optionally have been previously encrypted by a symmetric or asymmetric password to preserve the privacy of their contents (e.g. a password or a finger print). The data would thus not be publicly accessible and only the owner of the decrypting password could access this data (e.g. central electoral authorities).

Once the validation test is generated, the method provides a second communication step for communicating to a consolidation module of at least said validation test. Optionally, in the event that the consolidation module does not have the local results, such results could be communicated together with the local recount information. Both the local results and the validation test could also optionally be completely or partially encrypted (e.g. only the parts that are considered important to be kept secret, such as the credentials or biometric records) before being communicated. This encryption will allow assuring the privacy of the local results and/or of the validation test in the cases in which it is required. The encryption could be carried out indistinctly by means of a symmetric or asymmetric system, provided that the decrypting password is in the position of the authorship responsible the consolidation module.

In a third step of the method, the results consolidation module will verify if the communicated validation test has been generated by the appropriate local electoral authorities. To that end it will verify if among the credentials, biometric tests, digital signatures and/or any identity test contained in the validation test, the identities of the local authorities responsible for performing that validation are included. In this sense the validation test may contain, apart from the identities required for this verification process, the identities of other electoral authorities that may be used in other subsequent results audit processes. In a basic embodiment, the validation process would take into account all the identities contained in the validation test. In an alternative embodiment, the verification process would only verify some of the identities contained in the validation test. For example, the identification test could be formed by the digital signature (e.g. generated by an electoral administrator) of the identity tests of the members of the polling station, the latter being able to be encrypted. In this case, the validation could be performed only on the identity of the electoral authority that has performed the signature and the rest of the identity tests would not be taken into account. Therefore, if the latter were encrypted, it would not be necessary to decrypt them. This type of verification is useful in the case that the validation test is to be used in subsequent verification or audit processes. For example, the validation of the remaining identity tests could be performed in a second consolidation module which is in a more secure environment.

In the event that the validation test has been generated by means of mechanisms which allow linking said identity test to the local results information (described above) during this verification step the correspondence of the validation test with the local results could also be verified. If the mechanism is a digital signature or a MAC, it would then be verified that this MAC or digital signature corresponds to the communicated local result information. If the mechanism used is based on biometric techniques, it will be verified that the biometric record contains the local result information, part of it or an integrity test of such information (depending on the process used in the validation step to generate the validation test).

Once the validation test is verified, the invention will proceed to a fourth generation step for generating a receiving test, which will contain at least the result of the verification. This result of the verification contained in the receiving test can be a numerical value, alphanumerical value, a text or the combination thereof. For example, a 1 could be used to represent that the verification has been correct or a 0 in the event that it is incorrect. A value or text can also be established for one of the cases (e.g. 1) and the other one can be left open to any other value different from the previous one (e.g. any text or value different from 1). In an alternative embodiment, in the event that the verification is positive, the receiving test could contain an acceptance test generated from at least part of the local result information of the verified validation test. This acceptance test could be a digital signature or MAC applied on at least part of the local result information or a unique identifier of these local results. Therefore, based on the acceptance test contained in the receiving test, it could be verified if the verified local electoral results from the previous step correspond with those validated by the local electoral authorities.

Alternatively, the acceptance test could contain a subset of information of this signature, a summary (e.g. cryptographic) of the signature or a subset of the information of the hash of this signature. The objective would be to generate an acceptance test that had a size that can be used for a visual or audible representation of this acceptance test.

In the event that the verification is positive, the consolidation module could store the local result information if necessary. In this same case and also optionally, the consolidation module could also store the validation test together with the result information or independently. Both the election result information and the validation test could be stored in the same module that performed the verification or in an additional consolidation module.

Finally, in its basic embodiment, the method provides a last communication step for communicating the receiving test to at least the local electoral authorities that generated the validation test. These authorities are thus informed of whether or not the validation test and the local electoral results have been accepted.

Optionally, in the event that the receiving test contains an acceptance test, said acceptance test could be used to verify that the verified local electoral results are the same as those previously validated. For example, it could be verified if the signature contained in the acceptance test corresponds with the local electoral results validated by the local electoral authorities. This acceptance test could also optionally be included in the official records of the electoral results generated by the local authorities. For example, the acceptance test could be printed or written in the official records of the presential results of an electoral college or precinct. It could thus be verified if the results contained in the record have been communicated and accepted by the consolidation module, verifying the existence of the acceptance test in the record. If the acceptance test was further generated from a digital signature of the local result information, the integrity of the record could also be verified, checking that the results reported therein correspond with that of the signature contained in the acceptance test.

At this point of the invention, the results consolidation (or global election recount) based on the set of local electoral results accepted by the consolidation module could be carried out. These local electoral results could have been stored by the same consolidation module as described above or could have been stored by means of other processes independent from the steps mentioned in the invention. In the case in which the local result information is partially or completely encrypted by the local electoral authorities, an additional decrypting step to decrypt said information will be performed before consolidating the results. This decrypting process could be performed in a consolidation module. The decrypting would be performed using the private password in the possession of a single member of the central electoral authority. Alternatively, the private password could be held by a group of members of the central electoral authorities. This would be possible by means of a secret sharing scheme, in which each electoral authority possesses part of the private password. To carry out the decrypting, all or a predetermined subset of the electoral authorities must collaborate to reconstruct the password and then carry out the decrypting.

Additionally, before consolidating the results, a second validation step to validate the identities of the validation test that had not previously been verified could be performed. If the identity tests are encrypted, they will be decrypted using a process similar to the decrypting of the local result information described above. In the event that these identities do not correspond with those assigned during the election set up process, the local results information related to the rejected validation tests could be isolated. This local result information would therefore not be reused in the final consolidation. For example, based on the previous example in which the validation test contained the encrypted identity tests of the members of the polling station signed by an electoral authority, the validation of the identities of the members of the polling station would be performed in this step.

To end the process, the consolidation module could also perform the final results recount process.

In a practical embodiment of this method, the consolidation module could be completely isolated, i.e. with no network connection. In this case, the communication of the local results and/or validation test could be carried out through removable storage means. The local results validated by the local electoral authorities, along with the validation tests, would have been previously stored in said storage means. The removable storage means will be connected in the consolidation module so that the information contained can be read and subsequently processed.

In another practical embodiment of the present invention, it could have one or more intermediate consolidation modules. Each of these intermediate modules will receive the local results from previously assigned electoral management units. Each intermediate consolidation module will carry out the already described verification processes to verify the validation test, will generate the receiving test and send same. Once the intermediate consolidation modules have received and validated the information from all the assigned electoral management units, at least the local results information will be resent to the main consolidation module. Alternatively, each intermediate consolidation module will perform a recount of the local results received, in which case this partial recount could be sent to the main consolidation module.

In another practical alternative embodiment of the present invention, the results generated from two or more different voting channels can be consolidated simultaneously. Such channels can include, for example, those already mentioned presential electronic voting systems, systems of voting by Internet, voting by means of mobile telephony, voting by telephone (IVR), voting by mail and any other known voting system. In this embodiment, the vote reception and counting center for each voting channel would act as an electoral management unit, represented by electoral authorities. Therefore, the processes carried out for the consolidation of the results would be identical to those already described in the preferred embodiment.
